View 2 RepliesI am creating a reporting app that pulls information off of a Sql database and populates the data in a datagridview control (DVG). I am using tab pages (Tabcontrol), and I have about 10 tabs with within the control. What I have done is created a dynamic control that will populate in each tab page once the tab is selected. I am using a split container and in my split container.panel 1 is where all my buttons and search functionality will be. In my split container.panel2 to is where the main DGV control will be. I have got this to function properly, however now I am unable to add anything to my split container.panel1. I would like to add diffrent labels and buttons in the panel1 one without putting another panel on top of the split container.panel1, and also if i do this when I resize my container the panel will just sit there. I am using the selected index changed event to get my split container to show in each of the diffrent tabs

searchTab.TabPages(searchTab.TabPages.IndexOf(searchTab.SelectedTab)).Controls.Add(splitContainer1)

I'm using VB Express 2008 in Windows 7 64-bit. I'm working on a project with a datagridview bound to a MS Access 2007 database. I want to use the datagridview to add, delete and update the data in the MS Access database. When I added the database file to the project through the Datasource Configuration Wizard, I selected 'No' to copy the file to the project folder. The connection string automatically placed in the project settings is: Provider=Microsoft.ACE.OLEDB.12.0;Data Source="F:My MoneyDoBillsDoBills2009.accdb"* The 'Copy to Output Directory" property for the DoBills2009DataSet.xsd is set to '*Do not copy*'(and I've tried every other setting available). So, as I understand it, I am working with the original file, not a copy, and any changes (additions, deletions, field changes, etc.) are made directly to the original file. I have added the following code to the datagridview rowleave event: [code]I'll figure out a way to skip the update if nothing is changed, but for right now, it doesn't work. I've searched MSDN, the MS Community forum and several other forums for a solution and all I have found is what I already have and it doesn't work.I can make changes at run-time alright, but the exception it triggered when I change rows, and the data is not saved to the database file.When I close/re-run the app, the changes to the data are not thereThere has to be a way to save changes to the datafile, but I'm just not finding it.

The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.

Form 1 code
Me.Validate()
Me. CustomersBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.BoardingschoolDataSet)
[code]....
Therefore that code above works perfectly as both of them saves information to the Customers table and waitingforApproval.The problem is here:When I open form2 which recieves information from WaitinforApproval database table(and I see it getting it from there as tableadapter works), I want to save the received information to the customers.So I have two data sets in here. Just like above So here I have created a button called confirm/save the data to customers. Hence I put this code in confirm button:
Form 2 code
Me.Validate()
Me. CustomersBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.BoardingschoolDataSet)
And the current dataset set for this form is �waitingforApproval.So it doesn�t save the received information from waitingforApproval into the customers�
ok so i made it so i could save the information to a XML file but i want it to have multiple entries insted of having loads of files with so little information in them also i want it so if i click edit it would edit the file and one of the entries and load them in the form fields

But for example all USB drives are on different names like G, E, and F, they all vary so how do I make my keylogger save the information in a .txt on the usb.
1. How do I save a .txt file to a folder named "logs" on the USB?
2. How do I register the F1 and other keys that are not registered.
3. How can I get the program to close when the USB is pulled out?
i have two forms and two database tables in sql. my problem is that, in one form(form1) i can save information to another form (form2) but in form2 can't able to resend data back to form1.
Am using dataAdapters and dataSet to load the data into application.
Having been thinking about this issue but doesn't solve it. i mean shall i use select query or what?
In form2, i don't want to insert new information rather all i want is to resend the loaded data from form1 back to it.
